초록

본 연구의 목적은 사회경제적 특성에 따른 장사유형 선호의 결정요인을 도출하는 것이다. 우리나라는 '장사 등에 관한 법률'에 의하여 장사유형은 매장, 봉안, 자연장으로 구분하고 있다. 본 연구는 사람들이 3가지 장사유형을 선택함에 있어 그들이 가진 어떠한 사회경제적 특성이 영향을 미치는지 실증분석하였다. 이를 위하여 2017년 사회조사 자료와 전국의 장사시설 자료를 수집하였다. 그리고 매장과 화장을 상위 계층으로 하고, 화장의 하위 계층에 봉안과 자연장이 반영된 위계 구조를 구성하여 분석용 자료를 구축하였다. 구축된 자료를 바탕으로 네스티드로짓모형을 활용한 실증분석을 실시하였다. 실증분석 결과, 장사유형의 선호에 통계적으로 유의한 영향을 미치는 사회경제적 특성은 성별, 연령, 가구주 여부, 혼인상태, 전반적인 생활에 대한 만족도, 사회경제적 지위에 대한 계층의식, 월평균 가구소득, 주택 유형, 주택 점유형태, 도시 거주 여부로 추정되었다. 네스티드로짓모형의 결과는 직접 탄력성과 교차 탄력성을 산출하여 변수별 탄력성 계수를 근거로 해석하여야 한다. 따라서 본 연구는 통계적으로 유의한 변수들의 직접 탄력성 및 교차 탄력성 계수를 산출하였다. 산출한 직접 탄력성은 통계적으로 유의한 변수가 변화할 때, 각 장사유형의 선택 확률을 해석하는데 활용하였다. 그리고 교차 탄력성은 특정 장사유형을 선택하는 경우, 나머지 장사유형을 선택하는 확률이 어떻게 변화하는지 해석하는데 활용하였다. 실증분석 결과 중 주목해야하는 점은 자연장과 관련된 사항이다. 자연장에 대한 수요를 충족하기 위한 자연장지의 공급을 활성화하고, 자연장에 대한 인식 제고를 위한 노력을 기울일 필요가 있다. 이를 통하여 국토 공간을 효율적으로 이용하여야 할 것이다.

The purpose of this study is to identify determinants for preferred funeral methods depending on socio-economic characteristics. In South Korea, the Act on Funeral Services, Etc. categorizes funeral methods into burial, inurnment, and natural burial. This study empirically analyzes how and what socio-economic characteristics affect choices among these three categories. Data is collected from Social Survey 2017 and funeral facilities in the country. The data to be analyzed is developed in terms of a hierarchy which puts the burial and cremation methods in an upper class and the inurnment and natural burial methods in a lower class. Based on this data, a nested logit model is employed to conduct empirical analysis. The analysis indicates that those characteristics that have a statistically significant influence on preferred methods include gender, age, householder, marriage, satisfaction with life, class awareness, monthly income, housing type, housing tenure type, and living in city area. Each variable's modulus of calculated direct and cross elasticity need to be used to analyze the outcome of a nested logit model. In this study, the modulus of direct and cross elasticity are determined for the significant variables. The calculated direct elasticity is applied to analyze the likelihood of choosing each funeral method when there are changes in the significant variables. When a particular method has been selected, on the other hand, the cross elasticity is utilized to analyze changes to the likelihood of choosing the other methods. One of the most notable results is related to natural burial. In order to meet the demand for natural burial, it is necessary to provide more burial sites and raise awareness of natural burial. This will facilitate the efficient use of national territorial space.
